Took some time this evening and checked the voltage on several outlets
in my shop and to my surprise I found several at 117v and several at
125v. Then I noticed that the difference voltages were on different
circuits. Then taking a look at the breaker box I noticed that each 125v
would be directly across from another 125v breaker and the same for the
Well, that gave me a good clue as to what was happening so I opened the
box and took a look and checked some voltages. I took a picture, added
the voltages to it, and uploaded it to one of my domains at
http://www.dongares.com/breaker.html so go and take a look.
As I have previously mentioned in an earlier post this is a sub-panel
which is supplied from the main panel in my home via a 100 amp breaker.
I have not taken time to check but I am almost willing to bet that I
find different voltages in my home also. It is going to be interesting
to see if what I am getting from the street to my home is also different
voltages...how you want to bet?
The home was built in 1993 and these differences have never caused a
problem but it will still be interesting to see what is actually happening.
